The High Head Member (Church Point Formation, Goldenville Group, Meguma terrane, Nova Scotia) revisited: new information on relevance for early deep-water colonization

Abstract Trace fossils in the High Head Member display disparity thus far unique in lower Cambrian (upper Terreneuvian–Series 2) deep-water sedimentary rocks. This disparity is likely not because the organisms making trace fossils did not exist in other places but instead a result of the special preservation conditions—big exposures of tops of beds made of sediments of the right grain size and under modern-day weathering conditions that gradually are exposing trace fossils that would otherwise not be preserved or observable.
